Population justification: The population is estimated to number 2,500-9,999 mature individuals based on an assessment of known records, descriptions of abundance and range size. This is consistent with recorded population density estimates for congeners or close relatives with a similar body size, and the fact that only a proportion of the estimated Extent of Occurrence is likely to be occupied. This estimate is equivalent to 3,750-14,999 individuals in total, rounded here to 3,500-15,000 individuals.

Trend justification: Despite the scarcity of information on population trends, a moderate and continuing decline is suspected to be occurring, owing to the conversion and degradation of semi-arid habitats across the range.
